1. A lever connector for use with a separate receptacle having terminals, the lever connector comprising:
a housing configured to be connected to the receptacle; and
a lever rotatably provided on the housing and configured to be rotated in a locking direction which is one direction to be disposed at a connection locking position, so that the receptacle and the housing are pulled to each other to connect the terminals of the receptacle and the housing with each other, wherein:
the lever includes support plate portions rotatably supported by both sides of the housing and a connecting portion connecting the support plate portions,
the housing includes a wall portion formed with a hump portion protruding in a direction intersecting with a rotating direction of the lever,
the lever is formed with an inner protrusion portion protruding in an opposite direction to the hump portion and configured to be engaged with the hump portion by rotating of the lever toward the connection locking position,
the hump portion has a tapered surface gradually inclined from the top of the hump portion to the wall portion and in a protruding direction of the inner protrusion portion as extending in the locking direction of the lever, and
as the inner protrusion portion is slid along the tapered surface beyond the top of the hump portion to be always disposed on the tapered surface and to be engaged with the tapered surface, the lever is applied with a rotating force in the locking direction, so that the connecting portion abuts against the housing.
2. The connector according to claim 1, wherein the connecting portion of the lever is elongated, and the support plate portions project from opposing ends of the connecting portion in a direction that is perpendicular to the direction of elongation of the connecting portion.
3. The connector according to claim 2, wherein the lever includes a pair of support walls that are disposed between the support plate portions, the support walls projecting from the connecting portion in the same direction and parallel to the support plate portions, each of the support walls defining an interior planar surface, the interior planar surfaces being oriented so as to face each other and being separated by a gap.
4. The connector according to claim 3, wherein the inner protrusion portion includes a pair of lock protrusions that are each disposed on one of the interior planar surfaces so as to project in opposite directions that are parallel to the direction of elongation of the connecting portion.
5. The connector according to claim 4, wherein the support walls define beveled surfaces that are adjacent to the lock protrusions.
6. The connector according to claim 5, wherein the hump portion of the housing includes a pair of hump portions that are separated and oriented to enable communication with both support walls and lock protrusions of the lever.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A time-to-contact estimate determination system for generating an estimate as to the time-to-contact of a vehicle moving along a roadway with an obstacle comprising:
A. an image receiver configured to receive image information relating to a series of at least two images as the vehicle moves along a roadway; and characterized by
B. a processor configured to determine a scaling factor that defines a ratio between a dimension length associated with two features of the obstacle in a first one of the at least two images and the same length between the same two features of the obstacle in a second one of the at least two images and uses the ratio to generate a time-to-contact estimate of the vehicle with the obstacle.
2. A system according to claim 1 wherein the scaling factor defines a ratio between vertical dimensions of the obstacle in the images and uses the ratio to estimate the time-to-contact.
3. A system according to claim 1 wherein the scaling factor defines a ratio between horizontal dimensions of the obstacle in the images and uses the ratio to estimate the time-to-contact.
4. A system according to claim 1 wherein the at least two images comprises more than two images.
5. A system according to claim 4 wherein the processor processes the image information to determine a lateral displacement of the object relative to a position of the vehicle.
6. A system according to claim 5 wherein the processor determines a likelihood of collision responsive to whether or not the lateral displacement substantially uniformly approaches zero.
7. A system according to claim 1 wherein the processor generates a time-to-contact T in accordance with the expression T=1(S\u22121)\u0394T where S is the sealing factor and \u0394T is a time lapse between two images of the at least two images.
